(2)Check for shift shock and slip. Check for shock and slip at the 1
2, 2
3 and 3
O/D up±shift.
(3)Check for abnormal noise and vibration.
Run in D range lock±up or O/D gear and check for abnormal noise and v\
ibration.
HINT:
The check for the cause of abnormal noise and vibration must be done very t\
horoughly as it could also be
sure to loss of balance in the differential, torque converter, etc. (4)Check kick±down operation.While running in the D range, 2nd, 3rd and O/D gears, check to see that the p\
ossible kick±down
vehicle speed limits for 2
1, 3
2 and O/D
3 kick±downs conform to those indicated in the
automatic shift schedule (See page 03±45).
(5) Check for abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.

Drive in D range O/D gear, at a steady speed (lock±up ON) of about 60 km/h (37 mph).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in engine speed, there is no lock±up.
(b) S range test Shift to the S range, depress the accelerator pedal and check the follow\
ing points:
Shift operations.

Shifting the shift lever to º+º or º±º changes the shift \
range on the combination meter.
HINT:
Manual shift prohibition control is performed when:

Down±shifting causes engine overrun.

Down±shifting is required continuously, down±shifting to 1st gear may not be performed.
(c) R range test Shift into the R range and fully depress the accelerator pedal and check\
for slipping.
CAUTION:
Before conducting this test, ensure that the test area is free from peop\
le and obstruction.
(d) P range test Stop the vehicle on a grade (more than 5
) and after shifting into the P range, release the parking
brake. Then, check to see that the parking lock pawl holds the vehicle in plac\
e.

8. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R ranges.
NOTICE:

Do the test at normal operating ATF temperature 50 to 80
C (122 to 176
F).

Do not continuously run this test for longer than 5 seconds.

To ensure safety, do this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect the hand±held tester to DLC3 or tachome-
ter to terminal TAC of DLC3 with SST.
SST 09843±18030
(3) Fully apply the parking brake.
(4) Keep your left foot pressing firmly on the brake ped-
al.
(5) Start the engine.
(6) Shift into the D range. Press all the way down on the
accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,550
150 rpm
(8) Do the same test in the R range.
Stall speed: 2,550
150 rpm
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R ranges

Engine output may be insufficient

Stator one±way clutch not operating properly
HINT: If more than 600 rpm below the specified value, the torque
converter could be faulty.
(b) Stall speed high in D range

Line pressure too low

Forward clutch slipping

No. 2 one±way clutch not operating properly

U/D clutch slipping
(c) Stall speed high in R range

Line pressure too low

Direct clutch slipping

1st & reverse brake slipping

U/D clutch slipping
(d) Stall speed high in D and R ranges

Line pressure too low

Improper fluid level

U/D one±way clutch not operating properly

9. HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:

Do the test at normal operation ATF temperature 50 to 80
C (122 to 176
F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stopper outside the vehicle while the other is doing the test.

Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the rear side of the trans-
axle case and connect SST.

(3) Fully apply the parking brake and chock the 4
wheels.
(4) Connect the hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake ped-
al and shift into D range.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(9) In the same way, do the test in R range.
Specified line pressure:
